A2 tool steel is an air-hardening, cold-work grade known for its dimensional stability during heat treatment and its balance of toughness and wear resistance. This flat stock is manufactured to tight tolerances  -  thickness held to plus or minus 0.001 inches, width to plus 0.000 to 0.005 inches, and length to plus or minus 0.250 to 0.500 inches  -  making it suitable for precision tooling applications. Machinists, tool-and-die makers, and metalworking shops commonly work with this material to fabricate dies, punches, gauges, and cutting tools.\u003c\/p\u003e\u003cp\u003eThis flat stock is well suited for job shops and industrial tooling environments requiring a reliable cold-work steel with predictable air-hardening behavior. Its consistent cross-section and controlled tolerances allow direct use in die-making, fixture fabrication, and precision part production without extensive pre-machining. The 36-inch length provides practical stock for multiple parts per bar or for longer tool blanks. A2 grade is a common specification in North American tooling standards and is recognized under AISI classification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel  -  offers dimensional stability and reduced distortion during hardening compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment in tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches  -  holds close to nominal without undersize risk\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.003 inches ensures consistent right-angle geometry across the bar\u003c\/li\u003e\n\u003cli\u003e36-inch bar length provides versatile stock for multiple parts or long tool blanks\u003c\/li\u003e\n\u003cli\u003eWeight of approximately 1.01 pounds per bar for easy handling and freight planning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat bar suitable for cold-work tooling fabrication, including dies, punches, fixtures, and gauges in machine shop and tool-and-die applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with appropriate metalworking equipment, including band saws, milling machines, or surface grinders rated for tool steel. Always wear appropriate PPE including eye protection and gloves when cutting or grinding. Heat treatment to harden A2 steel should be performed by a qualified heat treater following established metallurgical procedures for this grade. Allow material to reach ambient temperature before measuring for final tolerance verification after any thermal operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus or minus 0.250 to 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02630820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52119249617202,"sku":"02630820","price":84.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_fcb31ba0-9072-4a2d-8c06-b74b2d6de95a.jpg?v=1790082886","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-02630820-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
